VAPOR-BURNER.

Specification of Letters Patent.

Patented Dec. 5, 1916.

Application filed September 5, 1916. Serial No. 113,541.

T all whom it may concern Be it known that I, MANNIN Gnoss, a citizen of the United States, residing at Council Grove, in the county of Morris and State of Kansas, have invented a new and useful Vapor-Burner, of which the following is a specification.

This invention relates to burners designed to use coal oil as a fuel, one of the objects of the invention being to provide a simple and efficient form of burner which will thoroughly vaporize fuel before it is admitted to the point of ignition, said burner including novel spreading means whereby the fuel is distributed to produce an extensive flame and whereby the heat generated is used for vaporizing the fuel contained in a vaporizing coil located under the flame.

A still further object is to provide a burner the parts of which can be readily taken apart to facilitate cleaning or repairing.

Another object is to providea burner which will utilize the minimum fuel while supplying the maximum temperature.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :Figure 1 is an elevation of the burner combined with a stove, that portion of the stove shown being illustrated in section. Fig. 2 is an enlarged central vertical section through the burner. Fig. 3 is a section on line 33 Fig. 2.

Referring to the figures by characters of reference 1 designates a feed pipe provided preferably at its lower end with a needle valve 2 or the like, this feed pipe being connected by a pipe 3 to a pressure tank 4 designed to hold air and fuel under pressure. The upper end of the feed pipe 1 opens into and is secured to a coupling 5 from which vaporizing tubes 6 diverge upwardly. These upwardly diverging tubes merge into an integral vaporizing coil 7 the central portion of which is bent to form a depending U-shaped hanger 8 from the center of which extends a nozzle 9. This nozzle is in line with the feed pipe 1 but before fuel can reach the nozzle it is necessary for it to pass from the coupling 5 through one or both of the diverging tubes 6 to the coil 7 and thence downwardly into the hanger 8. A cup 10 is connected to the coupling 5, this cup having the escape of fuel. Drain openings 17 are formed in the bottom plate 13 between the two flanges and these openingsare preferably produced by striking lips 18 downwardly from the plate, the lips serving to deflect drained fuel downwardly into the cup 10.

The plate 13 has a central opening 19 in which is mounted one end portion of a tube 20 forming a mixing chamber. A cap 21 extends over but out of contact with the upper open end of this tube and a peripheral flange 22 is provided on the cap and surrounds the uppcr edge portion of the flange 15. Secured to the upper end of the tube is a spreading member 23 in the form of an inverted cup, the lower edge of which rests on the plate 13 close to the flange 1.5, the peripheral portion of this spreading memher being slightly spaced from the flange 15.

For the purpose of insuring a firm connection between the plate 13 and the coil 7, said plate has depressed portions 2a which fit snugly between and are soldered to the convolutions of the coil.

In order to permit drainage of any liquid fuel which may accumulate within the depressed portions 2-1 through leakage under the edge portion of the spreading element 23, cars 25 are struck downwardly from the bottoms of the depressed portions to form outlet openings which will drain into the cup 10.

It is to be understood that any desired number of burners such as described may be used in connection with a stove a tion of which has been indicated at S. The fuel under pressure in the tank 4 is adpormitted to the burner by opening the valve 2 and is first heated by burning some coal oil in the cup 10 so as to cause the Contents of the burner to vaporize and issue in the form of a gas through the apertures 16. As the fuel issuing from these apertures is consumed the heat generated will be transmitted to the coil 7 so that fuel before'entering the burner will thus be vaporized and will be forcibly expelled through the nozzle 9 and mixed with air within the tube 20 after which it will be spread over the element 23 to the numerous apertures 16 provided therefor. The ignition of the fuel will occur above the plate 13 and between the two flanges lat and 15 and a circular flame of considerable intensity will thus be obtained. The cap 21 can be readily lifted off of the flange 15 and the spreading element 23 and tube :20 can also be lifted out of position, thus to facilitate cleaning of the parts. Cup 10 can likewise be readily removed.

What is claimed is zp 1. A burner including upwardly extending tubes merging into a coil, said coil having a hanger, a nozzle extending from the lower portion of the hanger, means for supplying fuel to the tubes, a base plate mounted upon the coil and having depressions interposed between portions of the coil, an annular flange upstanding from the plate, a foramino'iis flange upstanding from said plate, a tube extending through the plate and forming a mixing chamber adapted to receive fuel from the nozzle, and a cap on the foraminous flange and extending over the tube.

2. A burner including upwardly diverging tubes merging into a coil, said coil having a central U-shaped hanger, a nozzle extending from the center of the hanger, means for supplying fuel to the tubes, a base plate mounted upon the coil and having depressions interposed between portions of the coil, there being drain openings within the depressions and within the plate adjacent the periphery thereof, an annular flange upstanding from the marginal portion of the plate, afoi'aminous flange upstanding from the plate and concentric therewith, a tube extendin throiwh the late and formin a mixing chamber adapted to receive fuel from the nozzle, and a cap detachably mounted on the foraminous flange and extending over the tube.

3.,A burner including upwardly diverging tubes merging into a coil, said coil having a central U-shaped hanger, a nozzle extending from the center of the hanger, means for supplying fuel to the tubes, a base plate mounted upon the coil and having depressions interposed between portions of the coil, there being drain openings within the depressions and within the plate adjacent the periphery thereof, an annular flange upstanding from the marginal portion of the plate, a foraminous flange upstanding from the plate and concentric therewith, a tube extending through the plate and forming a mixing chamber adapted to receive fuel from the nozzle, a cap detachably mounted on the foraminous flange and extending over the tube, and a spreading element surrounding the tube and within the space surrounded by the foraminous flange;

4. A. burner including upwardly diverging tubes merging into a coil, said coil having a central U-shaped hanger, a nozzle extending from the-center of the hanger,1neans for supplying fuel to the tubes, a base plate mounted upon the coil and having depressions interposed between portions-of the coil, there beingdrain openings within the depressions and within the plate adjacent the periphery thereof, an annular flange upstanding from the marginal portion of the'plate,

a foraminous flange upstanding'j from the plate and concentric therewith, a tube extending through the plate'and forming a mixing chamber adapted to receive fuel from the nozzle, a cap detachably mounted'onthe' foraminous flange and extending over the tube, a spreading element surrounding. the tube and within the space surrounded'by the foraminous flange,'and a drip cup supported below the coil for the reception" of fuel draining from the plate.

In testimony that I claimthefor'egoing as my own, I have hereto affixed 'my. signature in the presence of two' witnesses;
